Abstract
Abstract A missile with adjustable flight controls capable of altering the missile's flight path is disclosed. The missile comprises an electric generator and control electronics. The electric generator is used in this invention both to provide electrical power to the control electronics and to regulate the flight controls. A mechanical connection is created between the generators rotor and the flight controls. The generator is electrically coupled to the control electronics through an electrically variable load. The control electronics alters the load which varies the rotational speed of the generator. This in turn affects the flight controls and the flight path is altered accordingly. The invention is small and compact, allowing its use in small missiles such as mortar or artillery shells.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
139 words
A missile with target sensor means comprising: adjustable flight control means; electric generator means having a rotor and a stator, the rotor and stator being mounted on two sections of the missile capable of rotary movement relative to one another, the rotor being mechanically coupled to the adjustable flight control means; variable electric load means coupled to the electric generator means for providing variable electric resistance; and control electronic means coupled to the target sensor means and the variable electric load means, the control electronic means receiving target location signals from the target sensor means and altering the variable electric load in response to the target location signals, the changes in electric load varying the rotational speed of the rotor which in turn varies the rotational rate of the adjustable flight control means, resulting in an altered flight path.
Claim 2
Dependent Claim
139 words
A missile with target sensor means comprising: adjustable flight control means; electric generator means having a rotor and a stator, the rotor and stator being mounted on two sections of the missile capable of rotary movement relative to one another, the rotor being mechanically coupled to the adjustable flight control means; variable electric load means coupled to the electric generator means for providing variable electric resistance; and control electronic means coupled to the target sensor means and the variable electric load means, the control electronic means receiving target location signals from the target sensor means and altering the variable electric load in response to the target location signals, the changes in electric load varying the rotational speed of the rotor which in turn varies the rotational rate of the adjustable flight control means, resulting in an altered flight path.
Claim 3
Dependent Claim
15 words
The missile of claim 1 wherein the adjustable flight controls comprise rotating external control vanes.
Claim 4
Dependent Claim
14 words
The missile of claim 1 wherein the adjustable flight controls comprise rotating control nozzles.
Claim 5
Dependent Claim
14 words
The missile of claim 1 wherein the adjustable flight controls comprise rotating air spoilers.
Claim 6
Dependent Claim
38 words
The missile of claim 1 wherein the rotor of the electric generator means is coupled to adjustable flight control means comprising external air vanes, the air vanes being set into rotary motion by the airstream over the missile.
Claim 7
Dependent Claim
18 words
The missile of claim 5 wherein the external air vanes are in the forward section of the missile.
Claim 8
Dependent Claim
17 words
The missile of claim 6 wherein the external air vanes comprises the forward section of the missile.
Claim 9
Dependent Claim
19 words
The missile of claim 1 wherein the adjustable flight controls are driven into rotary motion by internal missile energy.
Claim 10
Dependent Claim
33 words
The missile of claim 3 wherein the rotor of the electric generator means is coupled to the rotating control nozzles, which nozzles are set into rotation by gas generated internally to the missile.
